Pros: Good sound quality. Good comfort.
Cons: Seems to be optimized for "aviation noise"
I would rank this headphone as No:1 among the noise canceling head phones in respect to sound quality.
Bose is to "bass heavy" for my likings, but were better when it came to nois canceling.
Sony were the best when it came to comfort, but not as good sound quality as the Senheiser.
All in all this is the best among the 3 I'v tried.
